CSRN085V0-G Equivalent & Substitute Parts

Part Overview

The CSRN085V0-G is a steering TVS diode manufactured by Comchip Technology, designed for transient voltage suppression in surface mount applications. This part operates with a 5V reverse standoff voltage and 300W peak pulse power rating across four unidirectional channels in an 8-SOIC package. The product is currently obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRN085V0-G is determined by the following critical parameters:

• Voltage - Reverse Standoff: Must be 5V to maintain circuit protection thresholds
• Type: Must be Steering (Rail to Rail) configuration with 4 unidirectional channels
• Package / Case: Must be 8-SOIC form factor for PCB compatibility
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -55°C ~ 150°C (TJ)
• Power Line Protection: Must support power line protection applications
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

All three substitute parts meet these core requirements while offering active product status and enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and REACH unaffected status, providing regulatory continuity for new designs and production support.

CDNBS08-SRDA05-4 (Bourns Inc.) offers the highest peak pulse current at 42A (8/20µs) with 14.6V clamping voltage, suitable for applications requiring robust transient suppression with moderate voltage headroom.

NUP4201DR2G (onsemi) provides 25V clamping voltage with 25A peak pulse current, appropriate for circuits requiring higher voltage margin during transient events.

SRDA05-4R2G (onsemi) delivers 12V clamping voltage with 10A peak pulse current, positioned for general-purpose applications with moderate transient energy levels.

All substitutes maintain the 5V reverse standoff voltage, 8-SOIC package geometry, and -55°C to 150°C operating temperature range of the original part. Selection depends on specific circuit transient energy requirements and voltage clamping specifications.

Frequently Asked Questions (FAQ)

Q: Can CDNBS08-SRDA05-4, NUP4201DR2G, and SRDA05-4R2G be used interchangeably with CSRN085V0-G?

A: All three parts share the same 5V reverse standoff voltage, 4-channel steering configuration, 8-SOIC package, and operating temperature range. Interchangeability depends on whether the circuit design accommodates the different clamping voltages (14.6V, 25V, and 12V respectively) and peak pulse currents specified for each substitute.

Q: What is the primary reason for substitution?

A: The CSRN085V0-G is obsolete. The three substitute parts are active products with current manufacturing support and inventory availability.

Q: Are all substitutes RoHS compliant?

A: Yes. CDNBS08-SRDA05-4, NUP4201DR2G, and SRDA05-4R2G are all ROHS3 compliant. The original CSRN085V0-G RoHS status is not specified in available documentation.

Q: Do the substitutes fit the same PCB footprint?

A: Yes. All substitute parts use the 8-SOIC (0.154", 3.90mm Width) package, providing direct footprint compatibility with the original design.

Q: What is the difference in power handling between the original and substitutes?

A: The CSRN085V0-G is rated at 300W peak pulse power. All three substitutes are rated at 500W peak pulse power, providing enhanced transient energy dissipation capability.

Q: Which substitute is closest to the original CSRN085V0-G specifications?

A: SRDA05-4R2G provides the most conservative clamping voltage (12V) and peak pulse current (10A) among the three substitutes, making it suitable for designs with similar transient suppression requirements to the original part.
